Description
Focused on insulation resistance measurements
Multifunctional meter of electrical installation parameters Sonel MPI-525 is an innovation in its category. It provides a wide range of
options for measuring the parameters of electrical installations, which makes it a recommended solution for installers as well as advanced
measurement engineers.
As one of the few meters on the market, Sonel MPI-525 has the ability to measure insulation resistance with the voltage up to 2500 V. Additionally,
the instrument enables automatic measurement of insulation resistance of 3-, 4- or 5-core cables or wires using the optional AutoISO-2500 adapter.
With the use of the MPI-525 meter it is possible to perform precise measurement of short circuit loop impedance (resolution 0.01 Ω) in L-PE circuits in
networks with RCD switches. Another valuable function of the device is the ability to measure the actual tripping time and tripping current of the RCD
breaker at a single tripping of the breaker.
Features
The meter offers a wide range of functionalities. It combines the measuring capabilities of several devices, while ensuring equally good accuracy.
The device can be used for all measurements for commissioning of electrical installations in accordance with applicable regulations:
Testing the insulation with a voltage of 2.5 kV
The unique feature of the meter is the option of measuring the insulation resistance with a voltage of 2500 V. Moreover, with AutoISO-2500 adapter,
the user may check RISO of 3-, 4- or 5-wire conductors and cables.
The device has a built-in timer. It may be used to set three different periods for measurements and result read-outs (in the range of 1...600 s).
It also automatically calculates two absorption coefficients.
In order to ensure safety of the user, after the measurement completion or interruption, the device automatically unloads the tested object.
Inspection of electrical safety
This device may be used to inspect safety of electrical systems in households and industrial facilities. Measurements can be easily automated with:
- auto mode of residual current devices (RCD) tests,
- AutoISO-2500 adapter for automatic insulation resistance test of 3-, 4- and 5-conductor cables, without switching
Increased resistance to environmental conditions
The meter will cope well in difficult environmental conditions. Protection against penetration of dust and water is ensured by a unique housing with a level
of protection IP54. It is resistant to mechanical damage, and a special design allows you to easily protect the screen by shielding using the cover of the meter.
In addition to the fact that it protects against damage, it also allows you to conveniently carry and use the device in different positions.
Communication and software
You can easily transfer measurement data to your computer via USB port or wireless communication. In order to generate a report on measurements
for electric shock protection, use Sonel Reports PLUS software. Saving the downloaded data to the simplest formats and printing is provided by
free Sonel Reader software.
